Recent pilot projects by Belgian startup H2Congo show promising results – storing surplus hydro energy as hydrogen during rainy seasons, then converting it back to electricity during dry months. Congo isn't just about storing energy – it's sitting on 70% of the world's cobalt reserves.
[pdf] Salt River Project (SRP) and Google this week announced what the companies are calling a “first-of-its-kind” research collaboration to better understand the real-world performance of emerging non-lithium-ion long duration energy storage (LDES) technologies, hoping to accelerate the advancements needed to deploy LDES at scale.
[pdf] The project, one of the largest renewable energy developments in the country to date, will supply electricity to over 300,000 households, significantly improving power availability while helping reduce carbon dioxide emissions by more than 50,000 tons annually.
